Troubleshooting
Close and then re-open WinMark Pro while the Flyer head is powered up. This forces WinMark Pro to
re-initialize communications with Flyer. If communication is not established after this step, then close
WinMark, power down the Flyer head, wait 30 seconds, and then reapply power. When Flyer’s Status LED
illuminates green, open WinMark Pro.
Symptom:

The laser mark produced by FH Flyer is much larger or much smaller than the image drawn on the
WinMark Pro Drawing Canvas.
Possible Causes:
 The lens size specified in WinMark Pro does not match the lens installed on Flyer.
Check that the lens specified in WinMark Pro matches the lens currently installed on Flyer. In WinMark,
go to the Tools menu, select General Settings… , and then click the “Device” tab. Check the Lens prop-
erty to ensure the chosen lens is from the FH/Flyer list.
Symptom:

No marks or very light marks appear on the part.
Possible Causes:

The part is not positioned at the point of focus.
Locate the Final Test Report shipped with your marking head to determine the actual working distance of
the focusing lens. Refer back to Figure 3 -2, Working distance measurement, in the Operation chapter
and then measure working distance from the bottom of the focusing lens mount to the surface of the part
to be marked. Adjust the Z-axis of the mounting platform or the marking surface as required to obtain
the cor-rect working distance.
Symptom:

Mark quality deteriorates over time and/or laser power must be increased to maintain mark quality.
Possible Causes:

The focusing lens has become coated with marking debris or vapor.
Carefully inspect and clean the lens as described in Maintenance in the Maintenance/Troubleshooting
chapter.
Symptom:

Pwr and Status indicators on the marking head are illuminated green, but no mark is made when the
Test Mark pushbutton is pressed or when marking is commanded through WinMark Pro.
